Hi rock!
I don't think you'll be able to fly professionaly here unless you have your JAA ATPL. I've just completed a licence conversion myself. I used to fly the Metro too.
Do a search here in pprune's wanabe's so you can read about the licence conversion, as there are quite a few hoops to jump through. Good luck if you decide to convert. I can tell you, you're going to need patience, stamina and lots of cash.
A few weeks ago there was a SA227 job advertised in airline appointments
www.uk-aa.com it think it is.
Well good Luck!
